After i put these remo heads on, the bass drums just blew me away! It gave them the attack and punch and the good bass drum BOOM you look for, without losing any punch. The 7" diameter hole is perfect for situations where you don't have mics for your bass drum, or you have some low quality mics, because you get massive sound. Great product!

I'm in a situation that i cannot afford expensive drum mics, and need as much sound as i can get out of my bass drum. I read that the hole in the middle of the head lets too much air out and not enough sound out, but boy, this head has made my bass drums just shoot out devastating, booming thuds. Accompanied by an Emad batter side, you've got one heck of a booming bass drum. Try it!
